You can put this solution on YOUR website! The Standard Form of a Linear Equation is:
The General Form of a Linear Equation is: although it is sometimes called the Standard Form.
.
Deduct 3x from both sides of equation, we get:
Now multiply by -1 on both sides of the equation, we get: <--- this is the proper Standard Form of a Line.
.
If we add 7 to both sides of the equation, we would then get the General Form of a line.
.
Done! :)
